Secrecy, Privacy, and Deception: The Mathematics of Cryptography

Every time we go on-line to look up something or to make a purchase, we are exposing ourselves to a certain amount of risk. We risk having our identities hijacked and our private information exploited. How do we protect networks against intruders and keep information safe? We do this with cryptography. This lecture will tour the mathematical ideas behind encryption, public key encryption, digital signatures, and authentication.
